He Cheated and Deleted the Evidence

I 35F caught my husband 33M cheating and got him and his AP to admit it a few months back. He quickly deleted all the messages on his phone for himself and the AP's that night. He was using Telegram. I DON'T NEED YALL YELLING AT ME TO LEAVE. That's done and gone.... I just want the transcripts for my divorce filings.

Is there ANY way to get those messages or pay a company to restore them? Everyone is telling me that Telegram doesn't restore deleted messages and no way to get them back once they are deleted.
